[osg-users] osgText crash - latest nVidia FX drivers

Hello everyone - I'm experiencing a crash using the latest nVidia driver when I bring up the stats window and am wondering if anyone else is experiencing the same problem. My hardware is a Dell Workstation using a nVidia FX4600 card. I'm convinced the issue is related to the driver upgrade. I was r

Re: [osg-users] The best way to make some object in a scene render after and infront everything else.

Hi Chris, If you are using several cameras to create the HUD, you don't need the renderbins anymore for this case. Every camera will only render the scene it has attached (addChild). You can control the ordering as seen in the osghud example, with osg::Camera::setRenderOrder(). Alberto El Jue

Re: [osg-users] The best way to make some object in a scene render after and infront everything else.

Hi Chris, If you want to clear the depth buffer then you need to use a separate RenderStage rather than just a RenderBin. A RenderStage is a special RenderBin that adds the frame buffer clear prior to its traversal, and any copy to image/texture operations after traversal. By default the OSG ha

For my case, once a box is piled, there's no need to move the object, I can even regenerate the whole entity if a change is necessary (this is a CAD app. not a game).

Hi David, Thanks for the suggestion... and the poetry! However, I think forcing the z-depth will suffer from the same rendering problems as switching off the depth test. i.e. the stuff in the overlay will not render correctly without depth value tests. With Roberts suggestion, if I can also work
